COLOR-BLENDING WHEEL.

SPECIFICATION forming part of Letters Patent No. 748,661, dated January 5, 1904.

A Application filed November 3, 1902. Serial No. 129,955. (No model-J To all zohom it mayiconcern:

Be it known that I, CHARLES SCOTT, a rosident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a simple whirlingor buzzing toy by means of which various colors and combinations of colore may be presented for the amusement and instruction of children and others. Various devices of this kind have been devised in the years past; but so far as I am informed the same have been of crude construction, difficult to arrange and adjust, and the colordisks have been loosely held or connected, so that it has been impossible to graduate the colors and obtain regular gradations of tints or blends.

The particular object of my invention is to provide a color-blending wheel that shall be made up of several colored parts and positive clamping means whereby the colored parts may be successively secured and held in predetermined relative positions whereby the development of a tint may be noted during a number of operations of the device.

Another object of my invention is to provide a whirling or buzzing toy that shall be of less cost and of more simple construction than kindred devices heretofore manufactured to the end that my educational and instructive device shall be marketable as a cheap toy- My invention consists generally in a plu-- rality of color parts or disks having central openings in combination with the hub fitting said openings and suitable clamping means for fastening said parts or disks upon the hub; and my invention further consists in various constructions and in combinations of parts, all as hereinafter described,and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawis a small perspective view of the wheel or buzzer. Fig. 4 is a sectional detail showing a modified construction of the hub. Fig. 5 illustrates a further modification of the hub and clamping devices, and Fig. 6 shows still another modification of this portionof my invention.

As shown in the drawings, 2 and 3 represent two disks of different colors. Each is provided with a large central opening for the hub or shaft and each also has one or more peripheral lugs 5 to be used in adjusting the disks. Each disk is split on a radius,so that the disks may be passed one upon the other to expose any desired portion of one contrast to the colored surface of the other. This adjustment is rendered easy by the edge lugs 5,

1 which may be grasped without pressing the disks together,which would prevent easy rotative adjustment of the disks.

6 is a hub or short shaft that fits the openings 4 of the disk and on which the disks are mounted. The hub 6 is provided with right and left threads '7 7 upon its ends to receive the threaded caps 8 9, which with their flaring edges 10 ll constitute the means for rigidly clamping the disks upon the shaft and in any position wherein the same are adjusted. The caps or screw-clamps 7 are preferably made of spun sheet metal and are very cheap. Two holes 12 12 are provided in the end of each cap for the twisting or whirling strings 13, by means of which the wheel or buzzer is caused to rotate rapidly in one direction and then in the other after the manner of the common buzzer-toy. When the wheel is thus whirled, the two colors that are exposed or present upon the surface thereof will blend together andprod'uce a mean color or tint, the depth or grade of which will vary for the purpose of matching or determining colors, tints, or blends.

The device may be made to reflect or produce the gradual shading or blending of one color into another by employing a colored eccentric part 14, having the curved or spiral edges 15, which in whirling produce the effect of the gradual domination of the disk color over that of the eccentric piece as the circumference of the disk is approached. By making the eccentric part 14 of less diameter than the disk the solid colors of the disk and eccentric may be produced at the periphery and center of the device, so that the whole course of the tint from center to circumference may be observed. As shown, the eccentric part is made double in order to maintain the balance of the wheel.

In order that the device may have value as a device for matching colors or detecting and determining the degrees of diflerence in certain tints or colors and become instructive asa toy, it is essential that means be provided for securing the disks and holding them in accurate relation after the same have been changed from one ratio of exposures to another,and for this reason I consider the clamping device to be the essential feature of my invention. In addition to the necessity for the clamping device as such it is desirable that the same be easy to operate or manipulate, so that the cards or disks may be changed with the least possible inconvenience or annoyance,and my devices are admirably adapted for the purpose.

A metal threaded tube may be substituted for the wooden plug or shaft 6, as shown in Fig. 4, and, if desired, one of the threaded caps may be dispensed with by the employment of the elongated cap 17 and the washer 18. (Shown in Fig. 6.) While I prefer to use two strings, one for each cap or part of the clamping device, so that the strings shall not interfere with the changing or placing of the disks upon the shaft or hub, I may employ the construction illustrated in Fig. 5,

using caps with open ends 19 and a middle partition 20, that is provided with holes 21 for the twisting strings.

It is obvious that various modifications of my invention will suggest themselves to one skilled in the art, and I therefore do not confine my invention to the specific constructions herein shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The color-blendingwheelcomprisingthe colored disks or cards provided with central opening in combination with the short shaft having threaded ends and the opposite screwcaps provided thereon, substantially as described.

2. The color-blending wheel comprising the colored cards having central openings in combination with the short threaded tubular shaft, and the screw-caps having clampingflanges and string attachments, substantially as described.

3. The color-blending wheel comprising the colored disks or cards provided with peripheral lugs and having center openings in combination with the double eccentric card having the curved edges 15 and a central opening, the short shaft or hub having right and left threads upon its end, the metal threaded caps having clamping-flanges and the twisting strings attached to said caps, substantially as described;

4. A whirling toy or buzz, comprising a short shaft or hub, in combination with colorcards having central openings to fit said shaft and self-holding caps removably provided on the ends of said shaft and together holding said cards against rotation thereon.

In testimony whereof I have hereunder set my hand, this 2d day of October, 1902, at Chicago.

CHARLES SCOTT.
